The new ProfiLine series includes three new families: 3110 Series, 3210 Series, and 3310 Series - all are rugged and waterproof with IP 66/67 rated performance. The separate battery compartment allows quick replacement of either standard or rechargeable batteries. The large, highly visible backlit LCD display provides excellent readability even in the most adverse lighting conditions. The easy-to-clean, high performance silicone keypad is completely sealed for water protection and features the touch and feel of traditional keys for error-free operation. A single battery pack (4 x 1.5 V AA) provides continuous operation of up to 2500 hours.

Functional and easy-to-use:
The 3110 Series
For people who want a reliable, simple and easy-to-use portable meter, the 3110 series is the right choice. The large, easy-to-read LCD display plus the simple six button keypad supports trouble-free and error-free operation. Available in two models: pH 3110 and Cond 3110 for conductivity measurements with automatic temperature compensation when a temperature probe is connected. Quick, at-a-glance readings are featured with the simultaneous display of both the parameter and temperature measurement. The new, simple 2-electrode graphite conductivity cell for use with the Cond 3110 is ideal for general purpose field applications. Or, use with the TetraCon® 325 4-electrode cell for enhanced performance – extremely wide measurement range with error-free results even when the electrode is soiled.

Convenient and versatile:
The 3210 Series
The 3210 series offers advanced measurement performance and menu guided operation with the pH 3210, Cond 3210 and the Oxi 3210 for dissolved oxygen measurement. All data information is displayed in plain text in your choice of 4 languages, English, German, French or Spanish. A special alert feature, CMC – Continuous Measurement Control, on the pH 3210 informs the user when measuring within the optimum range defined by the buffer solutions used. Manual datalogging allows storage of single readings including a time and date stamp. Each data set is fully displayed including value, temperature, day, time and ID.

The Oxi 3210 has the flexibility of connecting DurOx® and CellOx® 325 probes depending on application needs.
The Cond 3210 can be used with your choice of a wide range of standard and special application cell constants including standard WTW 2- or 4-electrode cells.

For customers looking for an easy-to-use DO meter, WTW offers the Oxi 3205 - a DO meter with backlit graphic display without memory functions.

High capacity datalogging: The 3310 Series
The 3310 Series is the best choice where high capacity datalogging is required. The pH 3310, Cond 3310 and Oxi 3310 are excellent for all traditional applications for in-the-field measurement. The high capacity memory for up to 5000 GLP compliant records together with a time controlled datalogger with adjustable intervals makes these instruments perfect for long term monitoring in field applications. The data is transferred using a built-in USB interface, the standard modern communication between instruments and PC.

The introduction of the ProfiLine Series again proves WTW’s dedication to meet customer demands for tailor-made portable products for the measurement of standard parameters. All instruments are available as packages including sensors, accessories and carry cases. Plus, a wide range of WTW sensors and accessories provides the solution for virtually any application.
